Problem: Igor the analyst has adopted n little bunnies. As we all know, bunnies love carrots. Thus, Igor has bought a carrot to be shared between his bunnies. Igor wants to treat all the bunnies equally, and thus he wants to cut the carrot into n pieces of equal area. 

Formally, the carrot can be viewed as an isosceles triangle with base length equal to 1 and height equal to h. Igor wants to make n - 1 cuts parallel to the base to cut the carrot into n pieces. He wants to make sure that all n pieces have the same area. Can you help Igor determine where to cut the carrot so that each piece have equal area?

<image> Illustration to the first example.

Input

The first and only line of input contains two space-separated integers, n and h (2 ≤ n ≤ 1000, 1 ≤ h ≤ 105).

Output

The output should contain n - 1 real numbers x1, x2, ..., xn - 1. The number xi denotes that the i-th cut must be made xi units away from the apex of the carrot. In addition, 0 < x1 < x2 < ... < xn - 1 < h must hold. 

Your output will be considered correct if absolute or relative error of every number in your output doesn't exceed 10 - 6.

Formally, let your answer be a, and the jury's answer be b. Your answer is considered correct if <image>.

Solution (in PYTHON3):

Solution:

def calcula(A , H):
	h = H/2
	passo = h/2
	a = (h/H)*h/2
	while(abs(A-a)>= 0.00000001):
		if a > A:
			h -= passo
			a = (h/H)*h/2
		else:
			h += passo
			a = (h/H)*h/2	
		if passo <= 0.00000001:
			break	
		passo = passo/2
	return h

x = input().split(' ')
n = int(x[0])
h = int(x[1])

A = 1*h/2
A = A/n
passo = A

for i in range(n - 1 ):
	print(str(calcula(A,h)) + ' ',end='' )
	A+=passo
